-Motor Current Signature Analysis (MCSA) has been successfully used for fault diagnosis in induction machines. The current spectrum of the induction machine for locating characteristic fault frequencies is used in MCSA. The spectrum is obtained using a Fast Fourier Transformation (FFT) that is performed on the signal under analysis. The fault frequencies occur in the motor current spectra are u...

This paper is concerned with a synthesis study of the fast Fourier transform (FFT), the short-time Fourier transform (STFT), the Wigner distribution (WD) and the wavelet transform (WT) in analysing the phonocardiogram signal (PCG). It is shown that these transforms provide enough features of the PCG signals that will help clinics to obtain qualitative and quantitative measurements of the time-f...

This paper proposes an interference suppression technique using edge-removal filter in the transmitter, as well as, nulling filter and turbo equalizer in the receiver for carrier interferometry (CI) based one-cell reuse single-carrier time division multiple access (TDMA) systems. In the proposed system, the desired signals in the reference cell are interfered by interference including adjacent-...

By mounting the transmitter and receiver of Frequency Modulated Continuous Wave (FMCW) Synthetic Aperture Radar (SAR) system on separate platforms, bistatic FMCW SAR offers more considerable capabilities, reliability and flexibility while maintaining the small size, low cost and agile reaction. The bistatic FMCW SAR raw signal simulator is highly required to quantitatively support the design of...

In today EW scenario the Radar features are getting advanced day by day. To intercept and analyse signals coming from such Radar, ESM receivers also should have modern and advanced features and techniques. There are many ESM Receivers developed/being developed based on Analog and Digital techniques to measure the intercepted Radar signal parameters. Frequency of the signal is one of the importa...

In order to solve the problem that violin performance evaluation is too subjective, this paper proposes a system based on mobile terminal technology. Violin sound mainly includes two indicators such as pronunciation quality and distance transmission ability. LabVIEW 8.2 used collect data, fast Fourier transform (FFT) analyze time-domain signal in frequency domain, process of discussed depth. Us...

We consider the template matching problem, in which one wants to find all good enough occurrences of a pattern template P from a larger image I . The current standard of template matching is based on cross correlation computed in Fourier domain, using the Fast Fourier Transform (FFT). This can be extended to rotations of the template by a suitable rotational sampling of the template. An alterna...

This study develops the preprocessing theory for time-reversal multiple signal classification (TR-MUSIC) imaging from the one-dimensional (time-domain) gating proposed in earlier papers to a two-dimensional one. Although the one-dimensional gating technique for TR-MUSIC mitigates the effect of noise as well as reduces the required number of antenna elements, the resulting image is subject to fo...

The new Proposed design has been designed and developed by novel parallel-pipelined Fast Fourier Transform (FFT) architecture. The most important and fastest efficient algorithm is a FFT. FFT is used to computes the Discrete Fourier Transform (DFT). FFT is mainly applied in autocorrelation, spectrum analysis, linear filtering and pattern recognition system. The proposed architectures were desig...
